Description

[Detailed explanation of the idea] The present invention relates to a crab farming device.

Conventionally, when cultivating young crabs in seawater, many young crabs are placed in a large aquarium, etc., but as the young crabs grow and molt their skin, they begin to eat each other and become more powerful. The survival rate was extremely low, with only a few strong crabs remaining, and in the worst case, only one crab remaining, and the disadvantage was that the price of the crabs also increased.

The present invention was developed to eliminate these drawbacks, and its purpose is to prevent cannibalism by isolating and cultivating crabs one by one, and to increase the number of crabs in the aquaculture room as they grow. The purpose of the present invention is to provide a crab farming device that can be gradually expanded.

That is, in order to achieve this purpose, the crab culture device of the present invention divides the box into a large number of culture chambers using vertical and horizontal partition plates, and the bottom net that forms the bottom of each culture chamber is placed inside the box. By making the vertical and horizontal partition plates removable, the culture chamber is configured to expand as the crabs grow.

An embodiment of the present invention will be described below with reference to the drawings.

Aquaculture device A is a long and narrow box body 1 with an open top surface.
The vertical partition plate 2 and the horizontal partition plate 3 are detachably formed, and the bottom screen 11 is stretched at a position near the bottom of the box body 1. The box body 1 is partitioned at required intervals in the transverse direction by horizontal partition plates 3, 3..., and the inner wall 4 of the box body 1 is divided into
A large number of small culture chambers 5 are partitioned by vertical partition plates 2 and horizontal partition plates 3.

The box body 1 is provided with a water supply port 7 on one side 6 and a drain port 8 on the bottom surface on the opposite side, and seawater is supplied through the water supply port 7, allowed to flow inside the box body 1, and drained through the drain port 8. .

Further, a required number of guide members 9 and 10 are provided on the short side inner wall surface and the long side inner wall surface of the box body 1,
The lower ends of the guide members 9 and 10 are aligned on the same plane, and the culture chamber 5 is placed under the guide members 9 and 10.
A bottom net 11 is stretched, and this bottom net 11 becomes the bottom surface of the
and the bottom 12 of the box body 1, there is a water channel 13 communicating with the
is formed.

The horizontal partition plate 3 has a cut groove 1 in the center that is open at the top.
4, and, contrary to the horizontal partition plate 3, the vertical partition plate 2 is provided with grooves 5 with open bottoms at required intervals.

Although the present embodiment is configured as described above, the specific configuration of the present invention is not limited to the above embodiment. It is also possible to partition the box into smaller aquaculture chambers by dividing the direction into several equal parts and attaching horizontal partitions to the vertical partitions.Also, the box used as the aquaculture device is not limited to the rectangular shape, but can also be semi-shaped. It may be circular or U-shaped, and there is no restriction on the shape.

The crab culture apparatus of the present invention is constructed as described above. Therefore, when forming the culture chamber 5, the horizontal partition plates 3, 3... are first placed in a state in which the openings of the grooves 14 are directed upward. Next, insert the vertical partition plate 2 into the guide members 9, 9 with the openings of the grooves 15, 15 facing downward, and then Cut groove 1 of partition plates 3, 3...
4, Insert it into 14. In this case, the depths of the kerfs 14 and 15 are adjusted so that the lower end of the horizontal partition plate 3 and the lower end of the vertical partition plate 2 form substantially the same horizontal plane.

After forming a large number of culture chambers 5 in the box body 1 as described above, seawater is supplied from the water supply port 7, and young crabs are put into each culture chamber 5, 5, . . . .
The water level in the culture chamber 5 is adjusted by providing an overflow pipe in the drain port 8 and adjusting the expansion and contraction of the pipe.

Young crabs of about 15mm grow to 50-60mm in about 2 months.
Grows into a crab. At this time, remove the vertical partition plate 2 that forms the culture chambers 5, 5..., expand the two culture chambers 5, 5 into one, and create a space of about 50 to 60 mm inside this expanded culture chamber. Add the grown crabs one by one. After about 6 months, the young crabs will grow to 15-20
Grows into a large crab of cm. In this case, every other or every second horizontal partition plate 3 is removed to create a large culture chamber, and the grown crabs are placed in the chamber for culture.

In this way, the crab culture device A of this embodiment is capable of expanding the culture chamber as the crabs grow from young to medium-sized crabs to larger crabs of 20 cm or more. This can be completely prevented with a board, and the survival rate can be improved like never before.

As explained above, the culturing device of the present invention isolates and cultivates crabs one by one, which prevents cannibalism and improves the survival rate.Furthermore, the vertical and horizontal partition plates are detachable. Since the cultivation room can be expanded as the crabs grow by assembling them, one cultivation device can grow everything from young crabs to large-grown crabs. be.

Furthermore, since the culture chamber can be assembled with simple operations as described above, excellent effects such as assembly and disassembly operations can be performed relatively easily.
